Ribose/Formula
What is deoxy ribose sugar?
deoxyribose, also called d-2-deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases. Deoxyribose was synthesized in 1935, but it was not isolated from DNA until 1954.
How many chiral atoms are in an acyclic structure of 2 deoxy D-ribose?
From this definition, D-ribose has four chiral centers, which are boxed in the structure above. The extracyclic carbon is not chiral because it has two hydrogen atoms attached to it. Therefore, there are four chiral centers in D-ribose.
What is the chemical formula of ribose?
How does the structure of a ribose sugar differ from that of a deoxyribose sugar?
The pentose sugar in DNA is called deoxyribose, and in RNA, the sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the 2′ carbon of the ribose and its absence on the 2′ carbon of the deoxyribose.
What is chemical formula of ribose?
What is a ribose sugar?
Ribose is a single-ring pentose [5-Carbon] sugar. The numbering of the carbon atoms runs clockwise, following organic chemistry rules. Note the absence of the hydroxyl (-OH) group on the 2′ carbon in the deoxy-ribose sugar in DNA as compared with the ribose sugar in RNA.
What is structure of nucleotide?
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).
What is the structure of sugar present in DNA?
DNA vs. RNA – 5 Key Differences and Comparison
| Comparison | DNA |
|---|---|
| Sugar | The sugar in DNA is deoxyribose, which contains one less hydroxyl group than RNA’s ribose. |
| Bases | The bases in DNA are Adenine (‘A’), Thymine (‘T’), Guanine (‘G’) and Cytosine (‘C’). |
| Base Pairs | Adenine and Thymine pair (A-T) Cytosine and Guanine pair (C-G) |
